LEVEL_BASED runs in production at BYU but will be replaced by BYU's new algorithm, Fair Tree. LEVEL_BASED has been committed to the SchedMD Slurm repository in the master branch for inclusion in 14.11 but will be replaced by Fair Tree. It is still available for 14.03.x through BYU's Github repository in the level_based branch, based off of slurm-14.03. See the README at the bottom of the github page for the current version number and installation details.

Contact Ryan and Levi directly or on slurm-dev with any questions and comments. Let us know if you try it out.

These percentages only report the utilization of the hardware. Current utilization is not necessarily
indicative of how long your jobs may wait to run.

Some jobs are preemptable and may be evicted the moment you submit new jobs. Others jobs
may be nearing completion and you might only have to wait a few minutes. Or maybe
the queue is so long and your priority so low that you'll wait for days.

The only way to know is to examine the queue or just submit your jobs. Don't assume that
100% utilization means "I might as well give up" because that is very likely incorrect.
Submit your jobs and hope for the best.
